Choppy Preformance with Wirless Adapter

Re: Choppy Preformance with Wirless Adapter

Interesting. Unfortunately it has been turned off for me this entire time. Shame, I would love not to be throttled at 100% all the time.

Re: Choppy Preformance with Wirless Adapter

Thank you all for the updates over the weekend. We're still doing some testing and Valve is continuing to improve SteamVR.

It does seem like there might be more than one root cause for this behavior though, so we've learned something new.

Thank you,

Re: Choppy Preformance with Wirless Adapter

I really hope the rest of the performance issues can be resolved.  I'm one of the people who had a major improvement with the SteamVR beta update.  It's still not perfect though.  Nvidia VR Funhouse and Budget Cuts are examples of games that are still unplayable.  Thankfully the issues only affects some area in Budget Cuts and there are significant sections that don't exhibit problems.  Nvidia VR Funhouse is a mess in wireless and completely unenjoyable, which is a shame as it's something my family enjoys playing.

 

@GettingSickOfThis,the Frame Timing graph in SteamVR is showing just that, frame timing.  It is not equivalent to utilization.  It's possible for your processor to be sitting at 10% and have frame timing through the roof and vice-versa.  That's why you can't directly compare Frame Timing and Utilization charts.

Re: Choppy Preformance with Wirless Adapter

Are you guys kidding me? My Wireless was running fine after i upgraded my whole system.. Now installed the latest steamvr.. and i cant play a Single Game!!!! Everything is super pixelated.. how can i roll back to the older version? And what happend

 

Seriously how can a company f** something up so bad.. I hope a good alternative is coming out soon.. I getting to despise HTC for all the Trouble they bing me and other consumers.. 

 

We pay the most of all VR Users and yet we get half ready products and software at our door.. Unbeliveable ...

HTC has nothing to do with SteamVR updates. If the latest SteamVR update is causing problems for you, post on the Steam community forums.

Re: Choppy Preformance with Wirless Adapter

Google Translate:
I also have the problem that the games are no longer running smoothly for me.
So you do not feel alone, I once made a video of this great problem. I compared the performance with different configurations. SS is 1.0
Is there a solution to the problem now?

Here is the video: https://youtu.be/iDeBdzjqkjQ

Re: Choppy Preformance with Wirless Adapter

@Goldenegg Yes.... Exactly my point. So Task Manager is the most accurate representation of hardware utilization. Wherein our CPU's are all endlessly locked to 100% irrespective of what game is being played whilst using wireless.


I can't add anything new to this issue and have gone back to wired until the issue is resolved. It was suggested to me that this issue didn't exist prior to the Wireless software Ryzen patch/update, shame rolling back to those pre bricked drivers/version isn't an option.

Re: Choppy Preformance with Wirless Adapter

The question is .... can Steam VR even solve the problem with software? Is Intel the problem? Was the problem recognized by the companies? Is this anybody interested in Valve or HTC?
The Windows Task: VR Compositor is listed as a separate process for the cable connection.
If the VR glasses are connected to the wireless adapter, the VR Compositor will be displayed as a subset of the "Steam Client Bootstrapper 32Bit".

The Steam VRCompositor needs about 5% CPU with cable
The Steam VRCompositor needs about 40% CPU with a wireless adapter
Intel 7700K / Asus Z270E

 

The device does not work acceptably. It is a disappointment.

Re: Choppy Preformance with Wirless Adapter

I have communicated with Intel directly on this issue and they are monitoring this thread. I must say that Intel customer service and tech support is mind boggling responsive and helpful; Kudos!

Also reached out to DisplayLink however they didn't respond.

As disappointing as it is, in defence of the Vive team their hands are clearly not idle. We'll have to wait and see.

Re: Choppy Performance with Wireless Adapter

After reading this thread, I think the result came from Nagorak makes sense to me. When go wireless and if you need to set your SS high, then you need to sacrifice the performance. That's why I set my SS like 100%.

--------------------------------------------------------------------------------------------------------------------

I haven't tested out to see if it was fixed, however I think I know why performance was bad before and why reducing SS helped improve performance. I discovered that if my GPU was completing the frame later, even if it was still below 12ms (staying out of reprojection), it would cause late starts on the CPU. Meanwhile if it was completing the frame faster this wouldn't happen.

Basically it seems like the Wireless Adapter inserted an extra step between the GPU completing the frame and the CPU starting the next(?) frame. It appears to work like this:

Wired: GPU completes frame > CPU starts next frame.

Wireless: GPU completes frame > WA Compresses Frame > CPU starts next frame.

So, if your GPU is finishing closer to the 12ms mark (usually what would happen if you are increasing SS to maximize image quality), then the CPU would end up starting late and if it was late enough it wouldn't finish in time resulting in reprojection. Meanwhile if your GPU finishes faster (lower SS), it gives more time to compress the frame before the CPU needs to start the next frame.

Assuming the problem has been fixed, I suspect what has changed is now the CPU is not being held back from starting the next frame while the previous frame is being compressed, and instead they are occurring concurrently.

Re: Choppy Preformance with Wirless Adapter

I am also having this issue. I get a little jutter every second or so. It seems to be worst in steamVR home and beat saber. I also get it in budget cuts. But I don’t get it much in SkyrimVR.

Specs:
Processor: i7-4790k
RAM: 16GB
OS: Win 10 Pro
GPU: GTX 1080


Things I have tried:
-reinstalling the software
-moving to all PCIe slots (both 3.0 and 2.0)
-reducing signal strength (moved close and far away and blocked the sensor). This had other effects like grey screen but the jutter was consistent.
-BIOS is at the most updated version I want (there is a beta for the next version, but I don’t want that)
-Windows is updated (as well as the latest steam and Vive)
-turned off all wireless signals in the house
-changed SS from 20% to 500% (normally 184%). No change in jutter.
-camera is disabled
-jutter is worst when I have a secondary video ouput via HDMI (2-3 jitters/second. It gets mildly better when out put is through DVI(1-2 jitters per second). Very little jitters when no secondary output(1-5 seconds between jitters).
-can’t find a setting to see if my PCIe is gen3.
-verified no jitters when wired with all the updates. Or with card still installed.
-CPU hovers around 50-70% depending on the game in VR (without wireless 30-50%)

Well, I hope this can be figured out soon. It’s just too expensive to have these jitters. I am willing to help troubleshoot or test anything you need in the mean time. I’ll probably give it another week before I return in.

Re: Choppy Performance with Wireless Adapter

Hi Alubaking. Are we reading the same thread because that link you provided points to a bunch of people with no awareness of the key issue (CPU throttling)  reporting supeficial improvements relating specifically to GPU performance whilst saying ABSOLUTELY NOTHING about their CPU usage; the OP included.

The OP (sergioberg79)  also said that "there is no performance issues with high SS settings for me" which completely contradicts your curious Nagorak theory. Mind you most of us here have tested with a wide range of SS settings with ZERO effect to CPU overhead; locked to 100% irrespective of conditions or troubleshooting.

To the contrary, most people here and there clearly pointed out that CPU use was exactly the same post update. Some statements from that thread you might have missed before posting here...
"CPU still spiking in those even with this update"
"CPU is still pegged around 99%"
"Cpu was pegged at 100% all the time."
"CPU still seems high"
"Totally killing my cpu"

False claims of the issue being "completely resolved" really aren't helpful to those still being effected.

PS: "I haven't tested out to see if it was fixed"   -   Thanks mate, very useful.

Re: Choppy Performance with Wireless Adapter

Edit: it’s not gone Smiley Sad but it is quite a bit better. In steamVR home I get a jitter about every 3-5 seconds. In beat saber, when I play on expert I don’t get any, when I play on expert+ I get one every 3-5 seconds. But it is tons better. So much so that I think I’ll keep it.

Guys I solved it!!! Well, maybe there is more than one issue, but I solved my issue.

Also, I do not know a lot about computers, I just grew up in a family of electrical engineers that work for Intel... so don’t be hating if I sound stupid!

Here is my theory: it is a PCIe lane issue. Almost all processors have 16 lanes. So if your graphics card is in a x16 slot, it will use all those lanes. Now if you add something into another slot, the graphics card will still try to use all those lanes but the additional card will squeeze some information across when it can. (16 lanes is a lot and bandwidth, but every now and then it just gets a little bottle necked).

My solution: force my graphics card to only use 8x lanes (this should be less than a 1% decrease in performance according to the “reliable” source that is google). Then I installed my wireless card in the x4 slot.


Steps taken:
1) in bios, set the default display PCIe slot to my x8 slot
2) installed graphics card (I did have to reinstall the driver, which I was not expecting)
3) installed the wireless card in a 3.0 (I tried my x1 2.0 slots but it cause my computer to keep restarting). I only had one slot left so that was the x4 slot (I wanted to keep the x16 slot empty)
4) play VR without any jitters

Anyways, maybe more people could try this set up and see if it solves their problem. I’m happy to help troubleshoot any other people’s issues on my machine. Good luck!!!

Also my CPU usuals went down a little with these changes by about 10%

Re: Choppy Preformance with Wirless Adapter

This seems funny but I changed pci port seemed to fix some issues but then I noticed that I couldn't access the vive wireless settings. So I uninstalled and reinstalled the vive wireless software. Voila runs way better
